Overview
The Powerex CSD3120H is a single SCR POW-R-BLOK™ module rated for 1200 Volts and 400 Amperes average on-state current. It features an isolated metal baseplate design suitable for phase control applications. Key electrical parameters include a peak forward blocking voltage of 1200V, RMS on-state current of 620A, and peak one-cycle surge current of 8000A at 60Hz. The device operates within a junction temperature range of -40°C to 125°C and provides 2500 VRMS isolation.
Feature Summary
- Isolated mounting structure allows integration with other components on common heatsinks
- Metal baseplate construction ensures low thermal impedance for efficient heat dissipation
Applications
- Solid state motor starters
- By-pass switching circuits
- AC and DC motor control systems
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm voltage and current ratings match application requirements. Ensure proper mounting torque specifications are followed during installation to maintain mechanical integrity and thermal performance. Confirm compliance with relevant safety standards before deployment in critical infrastructure.
Selection Notes
Select this component based on its 1200V blocking capability and 400A continuous current rating. Evaluate thermal resistance values to determine appropriate heatsinking solutions. Consider the di/dt rating and gate trigger characteristics when designing the drive circuitry to ensure reliable switching under various load conditions.
Part Context
This module belongs to the CSD3 series of Single SCR POW-R-BLOK™ modules from Powerex. The series includes variants with different voltage ratings, such as the CSD3160H which offers 1600V blocking capability while maintaining similar current handling characteristics.
Replacement Considerations
The CSD3160H serves as a direct functional substitute within the same product family, offering identical current ratings but with a higher 1600V blocking voltage rating. Verify physical dimensions and terminal configurations remain compatible with existing board layouts.
